Chemical Structure
Description
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
1-[3-bromo-2-hydroxy-5-(trifluoromethyl)phenyl]ethanone (CAS 1897342-52-7) is a high-purity analytical reference standard with the molecular formula C9H12BrF3O2 and a molecular weight of 289.09 g/mol.
1-[3-bromo-2-hydroxy-5-(trifluoromethyl)phenyl]ethanone (C9H12BrF3O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
